碳酸岩生油机制是石油地球化学的一个重要问题。世界石油储量的40％储集在碳酸岩中。1980年11月美国石油地质年会专门召开碳酸岩石油地球化学与生油潜力讨论会。碳酸岩中有机质的存在形式及生油机制与页岩有何区别?我们研究发现很多碳酸岩生油岩存在包裹于矿物中的有机质。人工热变模拟生油实验表明,它们可以转化为生油物质。近几年,我们进一步研究了碳酸盐矿物包裹有机质(以下简称晶包有机质)的地质分布、数量、有机组分特征及其生油意义。这一简略报导期望同行们共同研究。
Carbonate oil generation mechanism is an important issue of petroleum geochemistry. 40% of the world’s oil reserves are stored in carbonate rocks. In November 1980, the annual meeting of the American Petroleum Geology held a seminar on the potential of geochemical and petroleum generation of carbonate rocks. What is the difference between the existing forms of organic matter in carbonate rocks and the oil generation mechanism and shale? We found that many carbonate derived oil rocks exist in the organic matter that is encased in minerals. Artificial thermal simulation of crude oil experiments show that they can be converted into raw oil substances. In recent years, we have further studied the geological distribution, quantity, characteristics of organic components and the significance of oil generation in carbonate mineral enclave organic matter (hereinafter referred to as crystal bag organic matter). This briefing expects colleagues to study together.
